"....All you do is click to download the target package you want, for instance for American coins you would click on Larry P's Incredible 61 target US coins . This will download to your downloads file or wherever you have your downloads go. Open where it is downloaded but do not unzip the file. In a separate window go to your C:\Program Files\EtracEm-V1-en\datazips and then just drag the "61_US_coins.zip" file into the C:\Program Files\EtracEm-V1-en\datazips file. Now your E-Trac emulator has US coins added to it...."

I tried this method with the US coins and did as you stated. I go to the top left of the Emulator and click file, then target zip files, then 61 US coins and click that and an error message comes up stating "The file is not a valid target zip file". Please help, not sure if I missed a step or something further I need to do, thanks in advance!!!!!!!!!!!!
